JOSEPH CARL MAY RHOFER, OF NEW YORK, N. Y., ASSIGNOR TO THE AMER,- ICAN AUTOMATIC SPRAY PERFUME COMPANY.

APPARATUS FOR DISPENSING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 430,079, dated June 10, 1890.

Application filed May 29, 1889. Serial No. 312,550. (No model.)

To all whom t may concern,.- A Be it known that I, JOSEPH CARL MAYR- HOFER, of the city, county, and State of New' York, a citizen of Austria-Hungary, have invented certain new and useful Improvements in Apparatus for Dispensing Liquids, of which the following is a specification.

This invention relates to certain improvements in that class of apparatus in which a 1o person may obtain in exchange for a coin or token a supply of perfumery or other liquid in the form of a spray after releasing a locking mechanism by the dropping of the coin and permitting thereby the working of an air-pump by the lowering of a platform or treadle by the person desirous of obtaining a supply of perfumery.

The invention relates more specifically to certain improvements in the apparatus for zo dispensingliquids for which Letters Patent were granted to me, No. 405,846, dated June 25, 1889, the improvements being designed with a view of making the operation of the apparatus more reliable and elective, con- 2 5 structing the air-pump and its operating mechanisms in a more durable and permanent manner, and facilitating the return of the piston of the air-pump and of the operating mechanisms to their normal position.

3o The invention consists, primarily, in certain improvements in the operating mechanism of the air-pump for supplying compressed air to the perfumery delivering and atomizing devices; secondly, in the improved construc- 3 5 tion of the mechanism by which the piston of the air-pump is returned to its normal condition after each discharge of perfume by the delivering devices; thirdly, in an improved device by which the perfume-delivering de- 4o vices are set for the proper perfume to be discharged, and, lastly, in the improved construction of the coin-receiver, so that the same can be removed from the vending apparatus in locked condition.

The invention consists, further, of certain details in the construction, arrangement, and combi-nation of parts, as will be fully described hereinafter, and iinally pointed out in the claims.

5o In the accompanying drawings, Figure l represents a front elevation, partly in vertical section, through the casing of my improved apparatus for dispensing liquids. Fig. 2 is a vertical transverse section of the same on line c x, Fig. l. Figs. 3 and 4t are a top View and 55 a side elevation, partly in section, drawn .on

a larger scale, of the mechanism for operating the air-pump by which the atomizing action on the perfume is produced. Fig. 5 is a horizontal section through the upper part of the 6o apparatus, taken on line y y, Fig. 2, showing the supply-cock, the delivering-nozzles, and the device for indicating the perfume tobe delivered; and Figs. 6, 7, 8, and 8 represent, respectively, a detail vertical longitudinal section, a vertical transverse section, and a top view of the coin-receiving box and its connection with the coin-tube, and a vertical section of the closed coin-box detached.

Similar letters of reference indicate corre- 7o sponding parts.

Referring to the drawings, A represents the main frame of my improved apparatus for dispensing liquids. At the upper part of the same is arranged a horizontal partition B,on which are supported one or more-preferably three-receptacles C C for theliquid perfumery. The top part of each receptacle C is provided with au opening having a detachable screw or other plu g for conveniently iilling the 8o receptacle with suitable perfume. Each receptacle C is further provided with an ordinary atomizin g-tube t, which is bent forward toward the front part of the apparatus, so that its discharge end communicates with a nozzle n in the opening a of the front wall of the main frame A of the apparatus. Each atomizingtube 2f is extended downward to near the bottom of its receptacle C and connected with an air-supply tube t', the lower end of which con- 9o nects with the casing D of a hollow conical plug D', which is provided with apertures thatv coincide with the ends of the tubes t when the plug is turned on its axis in different positions in the casing D. The casing D and the plug D form together a cock, by which the compressed air is supplied by means of an air-pump E, which is located below the horizontal partition B, and which is operated by means of a treadle or platform mechanism roo and the weight of the person desirous of obtaining a supply of perfume.

The air-pump E is connected with the hollow plug D by arubber or other tube e, which passes through the partition B and enters into the rear end of the plug D. The closed front end of the sameis connected byacrankarm Z with a cog-wheel m, the shaft of which is supported in bearings of the front wall of the main frame A and provided at the outer end with a button or handle m for turning the air-supply plug D', as shown in Figs. 2 and 5. An intermediate gear-wheel m2 meshes with the gear-wheel m and with a third gearwheel m3, the shaft of vwhich turns in bearings of the front wall of the casing A and carries va disk'mf, on which are placed the names of the different perfumes to be supplied by the apparatus. The disk m4 is inclosed by a cap m5, having an opening m6, in which the name of the perfume selected appears on turning the knob or button m. The setting of the plug D to the proper perfume-receptacle and the setting of the indicator-disk m4 is thereby accomplished at the same time, and thereby any desired perfume delivered by the atomizing devices described.

When the indicator-disk m4 is set for the desired perfume, the air-pump is unlocked by dropping a coin into the coin-slot f at the front wall of the main frame A, said coin passing along a coin-tube F onto a lockinglever G, which is shown in detail in Figs. 3 and 4.

The coin-operated locking-lever G serves for unlocking the connection between the treadle or platform P and the air-pumpE, so as to permit the latter to be operated by the pressure of the foot on the treadle or the weight of the person standing on the plat` form. The platform P is supported by lugs 4p' on transverse pivots p of a fulcrumed lever L, the rear end of which is connected to a Vertical guide-rod Z, which is guided in sleeves of suitable brackets at the rear wall of the main frame A, as shown in Fig. 2. The ver-A tical guide-rod Z is made in two parts, which Y are connected by telescoping sockets Z2 and an intermediate spiral spring Z3, as shown in Fig. 2, said spring servlng as a cushion against n the weight of the body of the person on the platform and producing the gradual transmission of the weight to the mechanism for operating the air-pump E. The vertical guiderod Z is provided at its upper part with a rack Z4, which meshes with a gear-wheel Z5, that is placed loosely on a shaft s. The shaft s is supported in bearings of brackets S, which are attached to the rear wall of the main frame A, *as shown in Figs. 2 and 3. rlhe r0- tary motion ilnparted to the gear-wheel Z5 by the rack Z4 is transmitted by a pawl Z6, pivoted to said wheel, to a ratchet-wheel Z7, which is keyed to the shafts, so that thereby rotary motion is imparted to the shaft s. To the shaft s is also keyed a larger gear-wheel Z8, which meshes with a rack Zgon the piston-rod of the air-pump E, so that by the turning of the shaft s the rack Z9 and the pistony E of the air-pump are lowered and the air in the pump-cylinder compressed and supplied to the atomizin g and perfume-delivering devices. The rack Z9 is guided by a flanged pulley Zl0 on a transverse pivot-rodZu, which is supported in bearings at the'ends of the brackets S. The actuating of the air-pump E, however, can only take place when the lockinglever G is released by a coin delivered from the coin-tube to the pan-shaped front end of the locking-lever G. This lever is pivoted near its rear end to one of the brackets S and provided with a bent rear end that engages a weighted pawl g, fulcrumed to the pivot-rod ZH, so as to lift the same out of the teeth of a.

ratchet-wheel g o n the shaft s, as shown in Fig. 4L. As soon as this is accomplished the shaft s can be rotated by the transmitting mechanism operated by the t-readle or platform P, and the air-pump worked so as to supply the 4required quantity of air for the discharge of a spray of perfume.

To the lower end of the rack Z9, attached to the piston-rod of the air-pump E, is applied 2L bent arm ZW, which carries a set-screw Z13, the head of which is normally at such a distance below the lever G that the latter, on the dropping of a coin, will be tilted suffr ciently to release the weighted pawl g from the ratchet-wheel g', but prevented from dropping the coin from the front end of the lever G until the piston of the air-pump is moved in downward direction. When this takesplace, the locking-lever G by the weight of the coin on its pan-shaped front end is gradually lowered until the coin is discharged into the hopper-shaped upper end of a second coin-tube F', which conducts it into the coin-receiving box H. The locking-lever G remains in its lowered position until by the upstroke of the piston the set-screw Z13 lifts the lever G and returns the balanced pawl g into engagement i with the ratchet-wheel g', so as to lock thereby the pump-operating mechanism and prevent it from being operated until another coin is dropped into the coin-tube F. For returning the piston of the air-pump into its normally-raised position, a pulley t', that is actuated by a weighted cord 1", is arranged on the shaft S. The cord t" is wound up ou the pulley 1l during the downward motion of the pistonand thereby the weight raised or the spring set to tension. As soon as the pressure is removed from the treadle or platform, the weight produces the turning` of the shaft s and the liftingl of the piston, which takes place easily as the pump-cylinder is open at the top and the air is drawn in through an air-inlet valve G in the bottom of the pump-cylinder.

locking-lever prevents the discharge of an additional spray without the insertion of another coin into the apparatus.

For preventing the repeated spraying of the apparatus by successively depressing the treadle or platform P before the piston and its actuating parts have returned to their initial positions, the plug of the air-inlet valve G is provided .with a weighted lever e2, which rests on a pin e3 of a rack Z9 on the piston-rod. The air-inlet valve G is kept open during a part of the downstroke of the piston and closed when the lever e2 arrives in the posi- The valve G remains closed during the remaining part of the downstroke of the piston, so that the full force of the compressed air in the pump-cylinder is utilized forthe spraying operation. On the return of this piston a partial vacuum is formed in the pump-cylinder, and thereby the upward movement of the piston retarded. The repeated lowering of the piston by pressing on the treadle or platform P without depositing a coin would therefore not supply any spray. The rack Z9 is raised slowly by the return mechanism of the piston, as some air is drawnin through the atomizing-tube and air-cock. Then the rack Z9 is raised far enough that its pin e3 re-engages the weighted lever e2. The air-inlet valve G is opened, and thereby the piston returned quickly into its normal position. The weighted lever of the air-inlet valve acts thus in connection with the pin on the rack of the piston-rodras a safeguard against tampering with the apparatus and spraying the contents of the perfume-receptacles without the required equivalent in coin.

My improved perf u lne-delivery device may also be used with an automatic coin-operated weighing-machine, in which case only one perfume-receptacle is used, which is connected directly to the air-pump, so that the airsupply cock and the perfume-setting device can be dispensed with.

The coin-box H is located in an opening d in the lower front 'wall of the main frame A, and supported by horizontal bracket-plates o, having iianges at their rear ends. The coin-box H is provided with a hinged and locked door and with a top opening h, which registers with an opening h in the upper bracket-plate and with the lower end of the coin-tube F, as shown in Fig. 6. The opening h of the top plate r is contracted into a slot h2, which extends to the front edge of A yokeshaped standard tongue h4 is attached to the top plate r transversely across the slot h2, said spring serving for the purpose of producing the closing of the top opening h of the coin-box H whenever the same is removed from the apparatus by engaging a lug or pin hof a slide-plate h6, which is guided in ways at the under side of the top of the coin-box and moved into closed position. The pin h5 of the slideplate h6 projects through thc opening h in the top of the coin-box H and the slotted opening h of the bracket-plate r, so as to be engaged by the spring 71,4 when the coin-box is removed from the bracket-plates r. When the slide-plate h6y is closed, a spring-catch h7 at its front end engages a notch or depression hs at the under side of the top plate of the coin-box H, as shown in Fig. 8% The coin-box H is opened at the oflice, the coins in the same removed, and the catch of the slide-plate h6 released, so that the latter can be moved into its forward position, as shown in Fig. 6, in which position the boX is returned to the apparatus and reinserted into position therein. When the coin-box H is moved into its position between the bracket-plates fr, the pin h5 presses the spring h4 back and passes beyond the saine Without changing the position of the slideplate, While when the coin-box lis removed the slide-plate is closed by the contact of the. pin h5 with the spring h4 and locked bythe` spring-catch k7, so that none of the coins can be abstracted from the box until the same is opened at the ofce. The attendant in charge of the `coin-boxes has no access to the. same, as he simply removes a filled and closed coin-box and replaces the same with an empty one, the slide-plate of which is in open position ready to receive. the coins deposited in the apparatus in return for a spray of perfume.

Having thus described my invention, I claim as newr and desire to secure by Letters Patentl l.
